AB  - Expectations about alcohol's effects and perceptions of peers' behaviors and 
      beliefs related to alcohol use are each shown to strongly influence the timing of 
      drinking onset during adolescence. The present study builds on prior work by 
      examining the conjoint effects of within-person changes in these social-cognitive 
      factors on age of adolescent drinking onset. We related youths' alcohol status 
      (i.e., alcohol-naive, initiation during study, prior initiation) to increases in 
      positive and negative alcohol outcome expectancies (AOEs), as well as increases 
      in perceived peer/close friend alcohol use and acceptance, during adolescence. We 
      also investigated whether changes in AOEs and perceived social norms 
      prospectively predicted alcohol onset in alcohol-naive adolescents. Participants 
      were 1,023 adolescents aged 12.2 years on average at enrollment (SD = 0.98), 52% 
      female, participating in an ongoing longitudinal survey on substance use and 
      health behaviors. Positive AOEs, close friends' norms, and same-age peer norms 
      increased linearly, whereas negative AOEs decreased linearly. Changes were 
      attenuated for participants who remained alcohol-naive and increased for 
      participants who experienced initiation during the study. Furthermore, we found 
      associations between individual changes in AOEs and perceived social norms. 
      Finally, survival models revealed that onset of alcohol use was prospectively 
      predicted by stronger initial positive AOEs, as well as increases in close 
      friends' norms and decreases in negative AOEs over time. These findings emphasize 
      codevelopment of AOEs and perceived social norms, coinciding with, and predictive 
      of, onset of alcohol use, and point toward a unique role for within-individual 
      changes in identifying youth at risk for early onset of alcohol use. (PsycINFO
